Returns reference to hash of arrays: key = ifIndex, value = array of VLAN IDs. These are the VLANs which are members of the egress list for the port. It is the union of tagged, untagged, and auto ports when using HP-VLAN.

Based upon the firmware version HP devices may support Cisco Discovery Protocol (CDP), Link Layer Discovery Protocol (LLDP), or both. These methods will query both and return the combination of all information. As a result, there may be identical topology information returned from the two protocols causing duplicate entries. It is the calling program's responsibility to identify any duplicate entries and remove duplicates if necessary.

If multiple entries exist with the same local port, c_if(), with the same IPv4 address, c_ip(), it may be a duplicate entry.

If multiple entries exist with the same local port, c_if(), with different IPv4 addresses, c_ip(), there is either a non-CDP/LLDP device in between two or more devices or multiple devices which are not directly connected.
